Hi,

I have a V570 and I am planning on connecting it to an EX-A1,which is then connected to the I/O modules - will this be ok or do I need an EX-RC1?

Is the V570 compatible with an EX-A1?

Thanks in advance...

Not 100% certain, but I believe you can. You must use the correct connection cable though.

By the way, the direct replacement for the EX-A1 is the EX-A2X, not the EX-RC1. The EX-RC1 connects to the PLC using CanBus and is a REMOTE expansion adapter. The EX-A2X is a LOCAL expansion adapter, like the EX-A1.

Hi,

When I try and configure the hardware for my project it won't allow me to choose the EX-A1 as a remote I/O option.

Is there another way of configuring a V570 to an EX-A1 - see my setup below...

The EX-A1 is NOT a remote expansion adapter. It is a LOCAL adapter. Local adapters do not need to be specified in the Hardware Configuration. Just place your IO-DI16, IO-RO16, etc, modules on the DIN rail in the Hardware Configuration. The local expansion adapter is assumed.

Pls tell me that's not the finished rack?  If it is, please send me the unused DI & RO 16...I can always use some spares!   😀

1.  The EX-A1 or EX-A2X does not appear when you configure your expansion (not "remote") I/O.  This is a confusing feature of Unitronics.  Don't worry about it - it will work fine as long as you have the proper EX1-CAnnn cable connected. 

2.  We haven't sold the EX-A1 for many years.  The EX-A2X is the drop-in replacement and is an isolated unit.  They work better.

Hi;

 

The only catch in replacing the   older EX-A1  with the   EX-A2X  is the Cable also has to be replaced and the EXL-CABxxx  Cable is wired different to the Older Cable

and  HAS  to be   Plugged in a certain way -  PLC and EX-A2X Ends are different.

I'm only getting started so I don't have any wiring done yet. I do plan to use these modules in future but if one becomes available I'll gladly send it to you.

All,

Is a standard patch cable sufficient to connect a V570 to a EX-A1?  I have a standard CAT5 patch cable connecting them but it doesn't seem to be communicating.

gerard339,

For EX-A1 (gray boots) cable P/N EX1-CA100. Where 100 is a cable length in sm.

EX-A1  comes with a 1m cable.

For EX-A2X (yellow boots) cable P/N EXL-CAB100  Where 100 is a cable length in sm.

The EX-A2X comes with a 1m cable.  Other cable lengths can be purchased.  The maximum length is 20m.  All lengths available can be seen below:

EXL-CAB050- 0.5m
EXL-CAB100- 1.0m
EXL-CAB200- 2.0m
EXL-CAB295- 2.95m
EXL-CAB400- 4.0m
EXL-CAB500- 5.0m
EXL-CAB600- 6.0m
EXL-CAB1000-10.0m
EXL-CAB2000-20.0m

Cable side with a ~10 sm ground wire connected to PLC.

B.R.
